Hello Everyone

I migrated a KVM image testvm.qcow2 into Proxmox VE

The steps I did :

1- Create a VM on Proxmox with the resources as my KVM image testvm.qcow2
2- after that I moved my testvm.qcow2 to the /var/lib/vz/images/101
3- I just renamed testvm.qcow2 to vm-101-disk-0.qcow2
4- I then went to ProxMox and started the VM

It starts fine and I have the same VM that was on my KVM but I now have no networking.

my network device vmbr0

what can I do to fix this
 
Do you have a network device attached to the VM?
If so, check the network configuration in the VM to see if the device configured matches the actual one.
You can do so by running ip -details a.
Please provide the output of that command, as well as your network configuration in the VM.
 
Hi Mira ,

Yes there is a network device attached.

Please find the attached screenshot of ip -details a

Hello I have solved the issue.

When I migrated my vm from Kvm it had a different network interface from the one from the new vm on Proxmox

these are my steps that solved the issue:
grep -nr "enp1s0" (old interface name from kvm)

vim /etc/netplan/00-installer-config.yaml

change enp1s0 to the new interface in our case it was ens18

Reboot
 
Great that you've found the issue.
